Wheeled hand truck

Abstract

A wheeled hand truck incorporating a footplate; a segmented retainer flange; a left pin pivotally mounting a left segment of the retainer flange and allowing sliding flange motion to a clearance elevation; a right pin pivotally mounting a right segment of the retainer flange and allowing sliding flange motion to the clearance elevation; left and right stops extending downwardly from the left and right flange segments; and left and right pairs of sockets positioned for, upon alternative motions of the left and right flange segments toward and away from the clearance elevation, and upon forward and rearward pivoting of the left and right flange segments, alternately holding the left and right flange segments at laterally and forwardly extending positions.

Description

FIELD OF THE INVENTION[0001]This invention relates to hand trucks of the type which are specially adapted for alternatively performing turf aerating.BACKGROUND OF THE INVENTION[0002]Hand trucks of the type which are specially adapted for performing turf aerating are known (e.g., See U.S. Pat. No. 8,714,275 issued May 6, 2014 to Ng). Such known turf aerating hand trucks commonly incorporate and configure mechanical parts which produce economic waste, and excess complexity of moving parts. Such turf aerating hand trucks also commonly undesirably impose mechanical restrictions which interfere with attachment and utilization of more than a single pair of turf aerating tines.[0003]The instant inventive wheeled hand truck solves or ameliorates the problems, defects, and deficiencies described above by incorporating a specialized slide shaft and pivot pin functioning handle in combination with a matrix of pin and socket pivot stops.BRIEF SUMMARY OF THE INVENTION[0004]A first structural com...

AI Technical Summary

Benefits of technology

The patent text describes a design for a foot plate for a vehicle. The foot plate has two retainer flange segments that can move vertically up and down. These flange segments are connected to two pivot pins, which act as slide shafts. The length of these pivot pins allows for the flange segments to move from the upper surface of the foot plate to an overlying elevation, creating a clearance elevation. This design allows for smoother movement and better performance of the foot plate.

Problems solved by technology

Such known turf aerating hand trucks commonly incorporate and configure mechanical parts which produce economic waste, and excess complexity of moving parts.

Such turf aerating hand trucks also commonly undesirably impose mechanical restrictions which interfere with attachment and utilization of more than a single pair of turf aerating tines.
